Since we are using matplotlib, let's create a new virtual environment called plotting: $ mkvirtualenv plotting Now that we're in the plotting environment, let's install numpy, scipy, and matplotlib: $ pip install numpy $ pip install scipy $ pip install matplotlib First, we'll perform exploratory data analysis by Apache Spark SQL and magic commands with the Azure Synapse notebook. When you use the Sparkmagic kernel, the Amazon SageMaker notebook acts as an interface for the Apache Spark session that's running on a remote Amazon EMR cluster or an AWS Glue development endpoint. You can also use Matplotlib, a library used to construct visualization of data, to create a plot. Plotting in the Python kernel is usually handled by libraries such as matplotlib and seaborne. The moment I change it to sparkmagic, matplotlib is no longer importable.

The Top 5 Magic Commands for Jupyter Notebooks. Within your notebook, create a new cell and copy the following code. iPython magic function can be called with a command line style syntax. sparkmagic. This action ensures that the code is run locally on the Jupyter server. from IPython.display import display import matplotlib import matplotlib.pyplot as plt %matplotlib inline pdf.plot() # pdf is the pandas datframe I get the errors: unknown magic command 'matplotlib' UnknownMagic: unknown magic command 'matplotlib' Capture the output of Spark queries as a local Pandas data frame to interact easily with other Python libraries (e.g. sparkmagic. By using the magic "%%local" at the top of a cell, the code in the cell will be executed locally on the Jupyter server, rather than remotely with Livy on the Spark cluster. I execute : %load_ext sparkmagic.magics %manage_spark. Afterwards, the issue seems to be resolved.
